Ответ(ы) на вопрос:
1) 6-2у = 8-3у
6-8 = -3у +2у
-2 = -у
у=2
2) 15х+3=10х- 12
5х = -15
х=-3
3) -5х-11= -6х-12
х=-1
4) 3х+5 = 8х-15
20 = 5х
х=4
5) 5(х+3) = 27+3х
5х + 15 = 27 + 3х
2х = 12
х+6
6) 3у + 4 - 2у = 6
у = 2
7) 5у - 13 - у = у+14
3у = 27
у = 9
8) 3 ( 2х - 4) -2(х+3) = -2
6х - 12 - 2х - 6 + 2 = 0
4х = 16
х=4
9) 4у - 3 = 2(7-у) + 1
4у - 3 = 14 - 2у + 1
6у = 18
у=3
